Installation Notes and Tips

Verify the vehicle is a 2005-2023 Toyota Tacoma with a front upper ball joint application before installation. The tapered stud uses a 12 mm wrench size, and the cotter pin hole and castle nut support proper fastening where specified by the vehicle. Because this is a press-in style suspension component with threaded features, follow the service procedure for the Tacoma front suspension and inspect related hardware and surrounding wear items during replacement.
